1.2 FUNCTIONAL DESCRIPTION
Figure 1-2 shows a simplified block diagram of the EVB-LAN9360.
The EVB-LAN9360, assembled with a PDM microphone in MEMS technology and one
stereo audio codec, can be used stand-alone to directly test or implement several con-
figuration options (e.g., the board operates as a Talker and uses the Line In of the on-
board codec).
Apart from the stand-alone use case, the board can be easily extended with customer
components via on-board expansion connectors that allow external devices to be con-
nected.
If the board should be run in stand-alone operation or if it uses external components
can be configured by jumpers (simplified depicted in
Figure 1-2 ; configuration details
can be found in Figure A-1 .
